Hello,
I think it is a community Cichov in the district Trebic, according your message. There is a small village Radonin close to the Cichov community - maybe it is your Radimov?.Radimov is a village in Tabor district, but it is in southern Bohemia, , but if you are sure with Radimov .... then I will rather looking there. In history was the Cichov also called Brtnický Číchov (southern part) or Třebíčský Číchov (northern part). These were two separate land registers that belonged to each different noble estate (and different parishes). This makes it so confusing quest.
And parish records for it are on-line (http://actapublica.eu ) under parish Heraltice (until 1785) or Přibyslavice (since 1785) or Chlum (since 1785). The earliest records should be sought also in parish Kamenice u Jihlavy (ca 17th century...) and even also Třebíč - město (St. Martin), that's Trebic-city (also ca 17th century).
I looked briefly preliminary sketches to the Land Cadastre (ca. 1835), but the family names I could find there. This does not mean anything (they did not necessarily own the land).
